This lesson explores the properties of matter, focusing on solubility and the three physical states: solid, liquid, and gas. Solubility refers to the ability of a substance to dissolve in another, exemplified by food coloring in water (soluble) versus sand in water (insoluble). The physical states are characterized as follows: solids have a definite shape and size with non-moving particles; liquids have a definite size but no fixed shape, with particles that move more freely; gases have neither a definite shape nor size, with particles moving very quickly.

UNIT 2 PROPERTIES OF MATTER Vocabulary
SOLUBILITY • The ability of a substance to dissolve when mixed in another substance • Soluable (mixed) • Example: putting food coloring in water • InSoluable (still separate - layers) • Example: Putting sand in water
PHYSICAL STATES • Solid • Definite shape, definite size • Particles don’t move • Liquid • No definite shape, definite size • Particles move but not as fast as gas • Gas • No definite shape, no definite size • Particles move very fast
